[Characteristics of postoperative period in surgical treatment of chronic frontal sinusitis].

During the last 5 years 132 patients underwent frontal-ethmoidal trepanation. Recurrences were observed in 27 (20%) patients with nonspecific immune deficiency, frequent respiratory viral infections and microbial virulence. The major cause of recurrences was inadequacy of the frontal-nasal ostium. Recurrences occurred more frequently in patients with orbital and intracranial complications of frontitis, traumatic frontitis, and abnormal anatomic relations of the frontal and ethmoidal sinuses. It is recommended to carry out postoperative conservative therapy including antibacterial, antiedematous, desensitizing drugs as well as drugs stabilizing immunity and microcirculation. It is also recommended to follow-up patients during a year after frontal-ethmoidal trepanation because recurrent episodes occur mostly during this time period.
